摘要：

An NMR study of one new and several known abietane diterpenes isolated from the roots of Aegiphila lhotzkyana is described. In addition to 1D NMR, several 2D shift-correlated NMR pulse sequences (H-1-H-1-COSY, NOESY, HMQC and HMBC) were used to establish all the structures, and unambiguously perform the H-1 and C-13 chemical shift assignments of the new natural diterpene and three derivatives, the NMR data for which have not been reported previously. Revision of current data assignment for teuvincenone H is also suggested. Copyright (C) 2003 John Wiley Sons, Ltd.
